Creating a zone for building software

This guide below assumes you are on a LAN with DHCP. We will create a crossbow VNIC on your primary network interface (assumed to be e1000g0 here, adapt as necessary), which will operate as if the vnic was plugged directly into your local LAN.

Create a zfs filesystem

Here, we are disabling atime and sync to speed up builds. Note that setting sync=disabled may result in dataloss in a power loss/system crash scenario, so only enable it for your build environment if you don't mind losing data.
